Halo Zero is an excellent action game in the style of Contra and Metal Slug series, with a little Abuse thrown in for weapon aim. Play the role of Master Chief as you partake in more dangerous missions, but fear not all the weapons from the original has been translated faithfully to the 2D version.

The sprites are large and closely resembles their counterparts from the hit FPS, animation is smooth and you can actually drive a warthog in the game. A recommended effort if not for the use of licensed characters.
